Installing Power Windows (By-passing BCM)

[SMIT]

hey guys,

have been looking around the site for awhile but cant really find the info i need and my wiring diagrams don't tell me what wire is what, so:

I have already got the following parts:
window regs
main switch
vt Calais wiring loom ( i have cut out the window wiring out of the main harness)

I want to just start of with the drivers side door. I wll bypass the Bcm and just hard wire.

OK what wire colors do what and where do they go?
i guess i just need to know:
*power
*ground
*what wires goto the window reg

*do i need any relays anywhere?

Is that all i need.

Your help would be much appreciated

anyone?????

[lion_g]

yeahh anyone i want to do the same thing

[vn_v6]

is it the same wiring to do it on a vn aswell? i want power windows to lol

i can't remember the colour of the wire, but get one of those tester devices where you ground the device somewhere, and you put it up against the wires, put the car into igintion and press the switch button, keep moving the device on all the wires until you pin point which wire is the sender wire.

once you have found the wire cut it off and wire it straight to the other side of the loom (past the BCM). I did this at the point where the door loom connects to the main loom, cut the wire off the main loom and joined my new wire there. You will see the colour of the sender wire on the loom when you plug it in, just join your new wire to that wire, but on the main loom.

If you have ABS, you won't need to ground any wires as it will already be done. There should be wiring underneath your center console cover for the power window buttons, if you have that then installation will be really simple.

Another thing you might find, when i did my conversion i noticed that the front passenger door, when i pressed the buttons on the switch they were swapped, i'd press down and it would go up and vice versa, if you get this simply either cut and swap the wires, or take the wires out of the plug (you should just be able to pull them out) and swap them around.

Sorry for not being very detailed, i can't remember what that device was called to test the wire, might be just something simple like wire tester or something (using my mates tools and stuff so not sure what it was)

If theres anything else you need to know, check out the thread in the how to section on the forum, i think it's stickied.

bumpage....

what you are trying to do is complicated, you need a basic understanding of electricity and be able to read a wiring diagram. for someone to guide you through will be very time consuming

[SMIT]

i have an understanding in "electricity" and have studied automotive electrical technology i can read a wiring diagram unfortunately the only ones i can find don't tell me what each wire is what or what pin they are in the iso connectors, only where they go and what color they are.

I asked for people to help me not to question whether i can do the job or not

Hope this helps mate

I'm thinking you'll need some sort of controller, if you want the timeout and the autodown. I'm doing the same thing in my VS, and using the controller, loom and regulators out of a VN calais.
With everything connected where it should be, i have four empty pins... One for constant power, one for ground, one for ignition, and one for the drivers door. The ground and power are pretty obvious, because they're a smaller gauge. The other two are easy to test.

If you want to stick with the loom you currently possess, I hope you have a lot of patience. Using a loom that originally lead to the BCM will probably be a painful task... Because all the reg wires and switch wires would lead to the BCM, then the BCM decides what to do with them. I'm not even sure the VT switch block would have the right connections to do this, without modification. You'd need a DPST (Double pole single throw) switch that defaults to center off for every window, allowing you to reverse the current to the regulator depending on which way you flick it... And then you'd need to wire the child lock button in series with the rear switches. There's probably an illumination wire somewhere in there, but that's easy to deal with. And THEN, you'd still miss out on your autodown and ignition off timeout.... The only way i could think to deal with the timeout, is wire the switched side of two relays in parallel, one relay controlled by the ignition and the other controlled by the interior light. Ergo, the power windows will work if either: The ignition is on, or the interior light is on.

Following my screwed up train of thought here?

all you need to bypass the BCM to get the drivers window to work (without the auto down feature) is where the loom runs up to the dash from the floor you have to cut the Blue/White wire from the part the runs to BCM and attach it to the Blue/White wire that goes to the door loom to make it go up, to make it go down you have to cut the Green/Black wire that runs to the BCM and attach it to the Green/Orange wire that goes the the door loom.

to get power for the windows it is up to you,
you could run the orange/yellow wire to a relay and hook a wire that runs the acc (such as lighter) to signal the relay for power but make sure you run a fuse, this will give you power for the windows only when the ignition is in acc or run, so it wont have power when the ignition is off.
for earth its the Black/Blue wire you could attach it to the negative terminal on your battery or to a exisitng earth somewhere on the car

this exactly what i have done to my VT and have never had a issue

hope you understand this

i have attached a Notepad File with the details for the wire colour

cheers

Sweet thanks for the 2 above post should help out allot and should be able to get it going, one more question i dont have door looms for the window regs will that matter or is there a specific connector that is needed to connect to the window regs

Cheers guys!

[hitman1979]

i looked into that myself trust me its easier to just get new door looms mate

When i did it in my vt ss it was green/black and green/orange.

All i did was cut and solder them in the kick pannel on the drivers side as it was a bit tigh to get up at the bcm

[Adriianz]

how'd you guys go, anyone got them hooked up? im looking at doing this to my vt exec lol

[anarklov3r]

Guys, theres a place in coburg melbourne called

Electric life Aust
295 Sydney Rd
Coburg VIC 3058

They specialise inpower windows. This is thee guy that supplied me the blanking plugs for my door trims in my VN (to cover manual winder holes) The guy there can install the windows and all wiring for you for ~$200. I asked him about it a couple months back. You provide regs+ switchs, he makes his own looms and plugs and it takes about 4 hours. Well worth it i reckon. If my car didnt have power windows already, i would go to him

Hi, did all this on the weekend to my 2001 VX II exec. There is some wiring diagrams somewhere, I have them at home, so will let you know which wires need to be done.

There seems to be alot of different information around here, so will just write out my experiance.

The wiring harness goes all the way up to the doors. On the door harness plug located just inside the body, the 2 wires that stand alone on the top are up/down, with a white and black wire to the back doors for the child lock.

The three passanger doors work fine doing it this way, by just either cutting and connecting new wires to the switches/motors, but for the driver door, I found it easiest just threading a new wire direct from the power window motor straight through to the main windows control switch in the centre console. You don't get auto up/down, but it works with out issue. Also you need to remeber the fuses/ relays that go into the fuse box under the steering wheel. There where 3 things needed for mine.

I suggest getting proper looms for the back doors along with the switches, but for the front doors, you can wire them directly.

Another tip, if you don't replace the door trims, go down to clark rubber, and get 4 30mm plastic plaugs. they are 70c each and fill the holes for the handles for a pro look.

The wrecker I got them from was nice enough to throw in an SS silver dash surround and even the pop riverts! which have huge faces on them.

yeah your wiring digrams would be an added help as i havent had time do this yet

[csimmo]

Here you go
